ent No. 1,030,273 for applying a band ofv cement to a piece of leather.

It is desirable in machines for applying a band lof cement to a piece of stock that prov vision be made for varying the width of the band.

Accordingly one feature of the present invention consists of the combination with a cement applying member of means'for varying the effective surface of said member; and in the illustrative machine an adjustable shield isarranged for movement across the surface of the cement applying member.

In machines of this class a presser is commonly provided which holds the stock against the cement applying member, the

presser and applying member coperating to feed the stock. In a construction such as that shown in the patent referred to above, wherein the two members between which .the stock is fed occupy ixed positions with respect to each other, the band of cement is alwaysapplied to approximately the same locality on every piece of stock. lt is desirable, however, that the location of the band be under control.

Another feature of the invention, then, consists of the combination of a plurality of members between which the stock is fed and means for causing relative movement of said members to grip the stock between them, one of said members being adjustable longitudinally of the other. Besides theadvantage which such relative adjustment.

gives in locating the band of cement close to or spaced from the margin of the stock it should be noted that it also permits the presser to be brought into register with the exposed surface of the applying roll where Specification pf Letters Patent.

said roll is provided with a shield for controlling the width of the band of cement.

rlhese and other features of the invention, including certain details of construction and combinations of parts, will be described in connection with an illustrative machine and pointed out in the appended claims.

Figure l is a side elevation of an illustrative machine with a portion broken away.

and other parts in section to show clearly the construction of the machine; Fig. 2 is a plan of the machine shown in Fig. l with thes'pring 69 and certain parts above the work table removed; Fig. 8 is a view drawn to a larger scale than the preceding figures, showing in detail the cement-distributing and work-pressing devices, and Fig. 4 is a view from the rear of the machine, also with parts in section.

`'llhe cementing machine with which the vinvention is described as associated is of the same general type as the machine vdescribed in the said prior patent and comprises a closed trough or tank 1 for containing the cement. Projecting through an opening in the upper plate 3 of the tank, which forms the work table, is a cement applying roll 5 the surface of which is provided with in dentations and by the rotation of which the cement is brought into contact with the work, the work being maintained in contact with the said roll by an overhead presser roll 7 rlhe presser roll 7 and cement applying roll 5 are rotated through mechanism hereinafter described from a shaft 9'driven from an external source of power.

ln this embodiment of the invention the cement applying roll 5 does not dip into the cement as in the machine of the prior patent but it is arranged to bear against a frustoconical supply roll 11 which is mounted so as to extend into the cement and thus supply the cement applying rollf5 with cement as the latter is rotated, the frusto-conical rollbeing revolved fri'ctionally by contact therewith. The frusto-conical supply roll 11 is mounted upon a stud or spindle 13 projecting inwardly from the wall of the trough'l, the vstud or spindle being secured to the wall at such an angle `as to maintain the upper art of the conical surface of the roll l1 in parallel relationship with the-lower surface of the cement applying roll 5: tVithin the stud 1l a spring 15 is arranged which by diate member such as the plunger 17v tends to press it yieldingly into Contact with the 'cement applying roll 5. The provision of this auxiliary spring-pressed supply roll 11 insures that the cement is supplied to the cement rollin a more'regular manner and with greater certainty than has previously been possible.

The cement applying roll 5 is made of con siderably greater widthI than-the roll in the machine of the said prior patent, and a shield 19 .is employed that is adjustable in a direction parallel with the axis of the roll, so that any desired amount of the surface not required foruse may be masked or covered over. IThe shield 19 conveniently may be formed as a plate adaptediofslide on the table, the vplate having a portion 21 (see Fig. 3) shaped to conform closely to the projecting portion of the roll 5. Conveniently, the sliding plate 19 forms a support for an edge gage 23 which may be employed to guide the work, the said ga e being adjustably secured to the plate. onvenlently, the gage 23 ma be pivoted, as shown at 25, Fig. 2, to the p ate 3 so that it can be turned out of the way of the work when it is desired to apply cement to the central portion of the work.

rlhe means for adjusting the shield 19 backwardly or forwardly over the cement roll 5 may comprise, according to this embodiment of the invention, a hand lever 27 pivoted at 29 upon t e table or plate 3 of the tank 1, the said ever being connected with the shield by a link 31. By the operation of the hand lever ,27 the sliding plate 19 is'moved to cover more or'less of the roll 5 whereby the e'ective surface of said roll will be lessened or increased, and a wider or narrower edging of cement thereby be applied to the work.

As before stated, an overhead roll 7 is employed tol coperate with the cement applying roll 5, the overhead roll being mounted in an overhanging arm 33 that is fulcrumed upon the shaft 9 mounted in bearings on the ,y

casing of the trough 1 in such a manner that the overhead feed roll 7 may bebrought down into contan'ct with the work on'the roll 5 by a connection from a treadle as hereinvafter described. rlhe overhead roll 7 is narrow as compared with the width oftheroll 5 and 1s adjustable along a line parallel with the axis of said roll so as to act on the edge of the work` notwithstanding the width of the edging of cement being applied, or to act upon a line the distance 'of which vfrom the edge may be varied according to requirements. This adjustability 'ofthe' roll 7 -may be secured by'mounting it upon the shaft 35 by which it is'rotated in such manner that it can slide thereonY and providing it with a groove 37 with which a yoke piece 39 enf'1 mensen to the position desired in relationship to the edge gage 23 or to the effective portion of the' surface of the cement applying roll. The yoke piece 39 may also be formed with a recess 4.7 in-which is fitted a icleaning pad 49. that wipes ofi' any cement that may be on the overhead roll.

rlhe driving mechanism by which the various parts of the machine are operated is, as before suggested, treadle controlled and may convenient-ly be arranged as follows The shaft 9 upon which the overhang arm 33 hereinbefore referred to is centered constitutes the driving shaft of the machine and is provided with a loose anda fast pulley 51, 53 by which latter power may be applied from an external force tothe machine. the driving shaft 9 is a worm that gears with two worm Wheels one wheel 57 being mounted on the shaft 59 carrying the cement applying roll 5 and the other Wheel 61 being on the shaft 35 carrying the overhead roll 7. By this arrangement of the parts the'overhanging arm 33 can be turned on the driving shaft 9 to raise the overhead roll 7 from the Iwork without disconnection lof the worm gear by which said roll is driven.

To transfer the belt from the fast to the loose pulley and vice versa a belt shifter is em loyed, the same being mounted on a rod 6 that is adapted to slide in 'bearings on the machine frame, and is normally maintained by a spring. 69 in a position in which the belt is on'the loose pulley51.

To operate .the slide rod '67 from a treadle inopposition to the spring a bell-crank lever 71 is employed, which lever is fulcrumed on the'machine frame withone larm connected by a chain 73 or the like with the'treadle (not shown) and the other arm projecting into a recess in the slide rod 67. By this arrangement Whenthe treadle is depressed the bell-crank lever 71 will slide the rod 67 in its bearings and transfer the belt from the loose pulley 51 to the fast pulley 53 and thereby start the machine so that both the cement applying roll and the presser roll will be rotated land the work supplied with cement and moved along past the edge gage.

rlhe overhanging arm 33 which, as aforesaid, is centered on the driving shaft 9, is

ahted upon by a spring 75 or it may be so npon the work when the belt is transferred meneer) from the loose to the fast pulley. For this purpose a wedge block 77 is provided on 'theI slide 'rod 67 aforesaid which wedge block is so arranged that when the slide rod is moved to bring the belt on to the fast pulley 53 the wedge will engage an abutment 79 carried in the end of the overhead swinging frame whereby the said fra-me will be turned on the driving shaft 9 andthe roll 7 pressed against the work. The pressure of-the oll upon the work is exerted' yieldingly, and for this purpose the abutment 79 is acted upon by a spring 81 that surrounds av stem 89 forming part of the abutment. The stem 89 is screw-threaded, and nuts 91 screwed .on the stem and bearing on the swinging frame provide mea-ns for adjusting the extent of yield of the abutment .and the consequent` amount of pressure with which the roll 7 is pressed against the work. The adjustment of pressure upon the work can thus be regulated according to requirements.

Similar to the machine described in the said prior patent the machine of the present application is provided with a pair of strippers or scrapers 93 which are employed in the operation of the machine to regulate the supply of cement to the roll 5 during the operation of the machine and are used to close, when the machine is at rest, .the opening in the plate through which the cement applying roll projects. The said strippers comprise two levers of the first order centered uponvthe under surface of thetable ofthe trough. The levers are so shaped at their ends adjacent to the cement applying.

roll 5 as to close against the periphery of the same. The said portions tend to close and are kept in place by, a compression spring 95 placed between the other ends of the levers. Projections 97 from the levers are arranged to coperate with one another so as to cause them tomove together when one o-f the said levers is operated, and to enable this to be done an extension 99 from one of the levers is provided -which isengaged-by a push rbd 101 that is carried b an arm 103 projecting from the slide bar 6 hereinbefore mentioned.

The push rod 101 is adjustable longitudinally by means of a portion whichA 1s screw threaded in a boss of the arm 103 aforesaid so that the extent to which the strippers 93 vare moved from the roll 5in the operation of the machine can be varied according to requirements The push rod is secured in adjusted position by a nut 105 screwed upon the threaded portion. It will thus be seen that when the slide rod 67` has been moved to transfer the belt from the loose pulley 51 to the fast pulley 53 and lower the roll 7 on to the work, the strippers 93'- will be moved away from the roll 5 by the push rod 10l`engaging the extension 99 of the stripper lever, the other stripper lever being at the same time actuated through the coi'iperating projections 97.

` he operation -of the machine as a whole briefly stated is as follows When the operator depresses the treadle the slide rod 67 is moved in opposition to its spring 69 by the bell cra-nk lever 71. This movement of the slide rod 67 affects three mechanisms of the machine, nrst, it moves the belt from the loose pulley 51 to the fast pulley 53 and thereby drives through the worm gearing 55, l57, .61 the coperating cement applying roll 5 and overhead roll 7; secondly, the overhead roll 7 is -brought down yieldi'ngly into contact with the work by the wedge 77 on the slide rodl 67 engaging the yielding abutment 79 on the end of the overhanging arm 33;' and thirdly, the strippers 93 are moved away from the roll 5 to an amount predetermined by the adjustment of the push rod 101 to regulate the amount of cement applied to the work.

Previous to the operation of the machine yas above described, the operator will have .at the same timevthe overhead roll 7 will have 'been adjusted'by the screw nut 45 to bear upon the work at the desired place.
